Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier high-tech enterprise integrating R&D, production, and global sales. For over 15 years, our company has built a complete industrial chain system, specializing in B2B bulk supplies and engineered formulations for heavy industrial equipment, rotary screw compression, and automotive networks.
Under our proprietary flagship brand "Century Longhai" and our international strategic partner brand, the British "A Ba" series, we specialize in high-temperature stable, oxidation-resistant, and high-performance lubricants. Our products are fully backed and insured by PICC (People's Insurance Company of China), providing global buyers with commercial risk mitigation and quality assurance.
The term "Top Air Compressor Free Oils" represents a critical paradigm in modern air system engineering. Oil-free air compressors require no oil in the compression chamber, but the gearboxes, driving gears, and shafts still demand superior synthetic lubricants to prevent friction-induced heat. Conversely, oil-injected rotary screw compressors rely on premium synthetic separator oils to produce clean downstream air.
Standard mineral oils break down under high heat, generating carbon deposits, varnish, and sludge that clog filters, damage separators, and contaminate production lines. Shandong Longhai designs premium Polyalphaolefin (PAO) and synthetic ester base oils to maintain thermal stability up to 120°C, offering up to 8,000 hours of operations without varnishing, extending the lifespan of machinery and preserving the purity of air.
Our smart manufacturing facility in Shandong features automated pipelines, bulk raw-material storage, and multi-tier blending tanks, ensuring quick turnaround times for major wholesale buyers.
By investing more than 5% of our annual revenue directly back into R&D, Longhai maintains a state-of-the-art testing laboratory. We partner with universities and research institutions to design lubricants that withstand extreme operations.
Our packaging line uses high-precision metering filling heads that maintain a tolerance of 1‰ to 2‰. This automation improves filling speeds by 20% to 35%, ensuring quick production runs and fast logistics for high-volume B2B orders.
Our premium lubricants are engineered to meet the strict clean-air requirements of key industrial sectors.
Protects critical instruments from oil contamination during product formulation and cleanroom operations.
High-purity lubricants support clean air delivery in food-contact packaging lines.
Ensures oil-free, dust-free pneumatic control systems during high-precision semiconductor assembly.
Maintains viscosity under heavy loads and high operating pressures in harsh environment applications.
Longhai Technology operates under strict international quality management systems. We hold certifications for ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety).
Our automatic transmission fluids have earned official Mercedes-Benz approvals, showing our ability to formulate lubricants that meet the strict requirements of leading global automotive manufacturers. Every batch is analyzed in-house to verify wear protection, shear stability, and viscosity indices before shipment.
We supply customized base stocks, viscosity adjustment packages, and private label packaging to fit the regional markets of global industrial networks.
Our chemists develop custom semi-synthetic and fully synthetic formulations to match specific machinery configurations, local climates, and targeted viscosity profiles. We design oils to meet or exceed industry standards like API, ACEA, and DIN.
We accommodate diverse purchasing structures, handling both small-scale product trials and full container runs. Our packaging ranges from 1L bottles to 200L steel drums and large IBC containers.
Every custom batch comes with detailed MSDS sheets, technical data sheets (TDS), and SGS quality reports. We help our B2B partners clear regulatory audits and speed up their import processes.
We support private label partners with logo positioning, industrial label layout, translation services, and customs paperwork, helping you establish a strong brand in your target market.
Our Zibo facility is equipped with analytical instruments to inspect batch consistency, foaming tendencies, and load capacity.
Our structured workflow ensures quality, consistency, and clear communication from initial request to delivery.
Reviewing target applications, operating temperatures, and viscosity requirements.

Adjusting additive packages and synthetic base levels to meet your specifications.

Sending samples for laboratory and field trials to verify machine compatibility.

Batch blending and automated filling, followed by fast export shipping.

Providing ongoing batch analysis, oil testing, and custom brand updates.
Technical answers to help engineers and procurement teams evaluate synthetic oil characteristics.
